Abstract: The subject of this article is the prerequisites for the establishment of the doctrine of creativity in the philosophy of Early German Romanticism. The source of the romantic concept on creativity is the I. Kant’s “Theory of Genius”, the meaning of which the Romanticists spread onto the entire human nature. The article highlights and analyzes the two groups of prerequisites for the establishment of the Romanticist doctrine of creativity as the fundamentals of understanding. The first group includes the elements of historical approach, which gained widespread in the German culture of the late XVIII century, while the second group includes the concepts of nature and emergence of the language that manifested during this period. The research leans on the principles of historicism and dialectics, method of historical and philosophical reconstruction, as well as elements of hermeneutical and comparative methods. The author considered not only philosophical works dedicated to Romanticism, but also literary, religious, and culturological works on Romanticism. An opinion is substantiated that the philosophical and historical-cultural context of establishment of the concept of creativity in philosophy of the Early German Romanticism indicates both, rational and non-rational components, which is especially evident in the Romanticist Theory of Language. In this field, the methods of scientific study of language and culture naturally align with the idea of “poetic” origin of the language, which has religious-mythological grounds.
